On a similar note, the nodes that control where the crew stand are similar, in that they all attach to nodes. They are usually just three letters long and are all on the floor. For example:

SON - Sonarman's position,
RAD - Radarman's position,
TDC - TDC Operator (He's super good, so they don't need a TDC assistant)

So you can move the geography student round the side if you want. Hope that helps.
